title: [The bioavailability of zinc oxide nanoparticles. Study using methods of radionuclide indicators].
abstract: Zinc oxide nanoparticles labeled with 65Zn were administered once intragastrically to male Wistar rats. The distribution of radionuclide-marker (65Zn) was measured by gamma-spectrometer in tissue samples of animals the organs through 4 hours, 1, 3 and 5 days after administration, and in the wastes of animals through 1 since 5 days. The data obtained demonstrate for the first time the bioavailability of zinc trace element in the form of its oxide nanoparticles.
